Analysis of caspase 7 in TA-treated breast cells. (a) MCF10A, (b) MDA-MB-231, and (c) MCF7 cells were exposed to TA-crosslinked beads of varying concentrations for the time indicated. Western analysis of collected cell lysates indicated that caspase 7 is activated, as evidenced by the presence of cleaved caspase 7. Increased cleaved caspase 7 is observed in lysates collected from MCF7 cells. -Actin was used as a loading control.
